wifi: ath12k: move firmware stats request outside of atomic context

In ath12k_mac_op_link_sta_statistics(), the atomic context scope
introduced by dp_lock also covers firmware stats request. Since that
request could block, below issue is hit:

BUG: sleeping function called from invalid context at kernel/locking/mutex.c:575
in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 6866, name: iw
preempt_count: 201, expected: 0
RCU nest depth: 0, expected: 0
3 locks held by iw/6866:
 #0:[...]

Preemption disabled at:

 </TASK>

Since firmware stats request doesn't require protection from dp_lock, move
it outside to fix this issue.

While moving, also refine that code hunk to make function parameters get
populated when really necessary.
